The price of gasoline in the Sacramento area rose another 9.9 cents over the past week to an average of $3.87 a gallon, national gas price tracker GasBuddy.com said Monday.
That's on top of a 27-cent spike the previous two weeks among the 720 area stations surveyed by GasBuddy.
The current Sacramento-area price is 13.1 cents per gallon higher than it was a year ago and 39.1 cents higher than last month.
Nationally, GasBuddy said, the average price of gas increased 5.7 cents per gallon over the past week to $3.55 up 28.2 cents from last month and 7.2 cents higher than a year ago.
Gregg Laskoski, senior petroleum analyst for GasBuddy, said Winter Storm Nemo likely slowed the rate of price increases in the Northeast and Midwest.
But on the West Coast, he added, "motorists are less fortunate. With western refineries producing at 75 percent capacity, less than any other region, California has seen its average price increase by 14 cents per gallon over the past week, doubling the rate of increase over the same period for the rest of the country."
